Australidea Cheiromycina Crustospathula Kalbionora Malmidea Multisporidea Savoronala Sprucidea Zhurbenkoa Malmideaceae is a family of crustose and corticolous lichens in the order Lecanorales.

[4] Malmideaceae is similar to Pilocarpaceae, but can be distinguished from that family by thallus organization and ascus structure.

Malmidea species have a thallus made of goniocysts–spherical aggregations of photobiont cells surrounded by short-celled hyphae.

This characteristic is quite rare in the Pilocarpaceae, only found in the monotypic genera Calopadiopsis and Pseudocalopadia.

[2] The genus Zhurbenkoa, consisting of three lichenicolous fungi from South America and Europe, represented the addition of a new nutritional mode for the Malmideaceae, which until then had consisted of only lichen-forming associations between fungi and green algae.
